CAMP STOVE.

Application filed October 4, 1926. Serial No.7139,262.

This invention relates to camp stoves gen erally but more, particularly of a two '01 three burner type. r

The principal objects of our invention may be enumerated as follows: 7

First, the provision of amultiple burner camp stove wherein the burners are foldable into or out of one'section of a carrying case to permit stowing in a relatively com pact manner along with the other parts of the stove in the case. Thus. a two or even three burner stove having a master'burner and one or more dependent-burners and made in accordance with our invention is of about the same size as single burner Stoves at present available and is not as cumbersome and awkwardto carry along in touring and camping. v j

Second the provision in a camp stove of the character described of a carrying case comprising hinged sections arrangedto be swung into coextensive relation to provide a stove base for supporting the burners, and also the provision in connection with the! case sections of a novel and simple means for holding the sections rigidly in coextensive relation and a simple and practical form of props-0r legs which are foldable into an out of the way position alongside the case or to an extended operative position for use. i

Our invention embraces still other objects and advantages to be pointed out more- In the course of the following description IBfGIGIICGlSlDfiClG to the accompanying drawings wherein Figure 1 is an end view of the carrying case with all the appurtenances of the camp stove stowed therein for transportation;

Fig. 2 is a plan view of the case opened to show the arrangement of the burners when folded in the case and the fuel tank, grates, and other parts previous to the setting up of the stove;

Fig. 5 is a view similar to Fig. 3' of a modified oralternative construction show-' ing the provision of three burners instead. of two.

The same or similar reference numerals to as a cover.

is simply are applied to corresponding parts thr0ughout the views.

Referring for the present more particu larly to Figs. 1 to .4, it will be seen that the carrying case 6 is equipped with a handle- 7 so that it may be carried like a suitcase. A leaf spring latch 8' has pins 9 arranged to be received in openings in the end-walls of the case sections or trays 10 and 11. The former is elsewhere referred to as the main section inasmuch as most of the parts/of the stove are arranged to bestowed therein, while the other section is elsewhere referred The two sections are hinged together, as indicated at 12, and arranged to unfold from the closed condition shown in Fig. 1 to coextensive relation, as shown in Fig. 2,'whereby to serve as a stove base as appearsrin Figs. 3 and 4. When so extended the sections are arranged tobe held rigidly with their inner ends abutting, as appears in Fig.4, byaclasp shown at 13; The latter operates through registering openings 14 in the abutting walls of the case sections and comprises a buckle 15 ar ranged to. be engaged over a hook or other projection 16 provided'on a strap'17 riveted. to the wall of, the case section 10. The buckle 15 is pivoted at 18 to a toggle link 19 which in turn is pivoted at 20 to the wall of the case section .11. It is obvionsly'a simple matter to secure the sections of the case 6 in rigid, coextensive relation. the moment the case 'is'unfolded. The buckle 15 passed through the openings 14- and overthe hook 16 on the strap 17 whereupon the lever 19-is forceddown to the position shown in Fig. -4 where the pivot 18 is slightly past a dead center position with respect to the'pivot 20.

A master burner 21 which has a manifold 22 leading thereto is bolted, as indicated at 23, to the bottom wall of the case section 10. When the case sections are in rigid, co-extensive relation a foldable dependent or auxilits manifold 25 into the case section 11,"as

' indicated in Figfti. The burner 24 in itsinoperative position is stowed in the section 10 alongside the other burner 2-1 and in substantially the same horizontal plane therewith The two burners are pivotally connected by their manifolds'which seat on one another'on'finished surfaces at 26, t-herebeinga bolt 27 extending through the juncture of the two manifolds coaxially with the seat 26 and provided with a coiled Compression spring 28 to hold the two manifolds together in air-tight relation. The seat 26 is at such an angle that the burner 24 swings in a plane at an angle to the longitudinal axis of the extended case sections whereby to dispose the burner 24 in line with the burner 21 in substantially the middle of the case. At the same time, when the burner 24 is folded in, as shown in Fig. 2, it assumes a position close to and alongside of the burner 21 so as not to take up too much room in the case. Registering notches are cut in the abutting Walls of the case sections at 29 to permit the swinging of the burner 24 from section into section 11. Obviously, this construction permitsthe provision of a multiple burner camp stove without resulting in an article of such size that it would be awkward and cumbersome to handle and transport. The folding of the burners in the novel manner disclosed results in such coinpactness that it may safely be stated that the multiple burner stove provided is, whenfolded, no larger than single burner stoves of the designs available up to the present time. As a consequence of the bulky size of the two burner stoves at present available the camper will often forego the convenience of the additional burner and procure a single burner stove in order to have the compactness which, up to the present time, has been offered only in the single burner stove. As will be apparent from the foregoing, the

present invention provides a double burner stove with practically the same compactness as any single-burner stove now available.

The burners are supplied with fuel from the usual tank 30 which, in the present case, has lugs 31 provided thereon to hook into openingsprovided in the end wall of the case section 10, as shown in Figs. 3 and 4. The tank has a delivery tube 32 extending therefrom over the master burner 21 and having a nipple end 33 for reception in an opening in a hollow boss 34 provided on the manifold 22. A valve 35 regulates the feedin of fuel in the usual manner. A pocket or well 36 is provided in the manifold 22. Some of the liquid fuel is discharged from the tube 32 into this pocket when starting the stove and when ignited serves to preheat the fine stream of fuel for vaporization. In the course of a few minutesthe stove is ready to operate to furnish the full cooking heat. A valve 37 is provided on the tank 30 so that the tank maybe charged with compressed air in the usual manner. A hand pump 38,

shown in Fig.2, is provided for. this purpose. The key shown at 39 fits the. valve These appurtenances are stored in the case when the'stove is folded up, there being sufficient room alongside the burner-.24, shown in Fig. 2. The tank 30, onthe other hand, is received in the space'alongside the burner 21. A pair of grates 40 are stowed in'the case section 10 so as to fold over the burners when thestove is folded up. The

tions 10 and 11 are arranged to receive the grates in the manner shown in Fig; 3. I

When the burner 24 is extended for use, its flame may be extinguished or controlled by a valve42 threading in the outer end'of the burner. A pair of links 43 .and 44 pivotally connected, as shown at 45, are pivotally connected with the valve 42 at 46 thus permitting the folding of these links inside the case in themanner shown in Fig. 2, or the extension thereof through an opening in the end wall of the case, as shown in Fig. The end link 44 in adjusting the valve is swung at an angle to it's companion link 43, as shown in Fig. 3, to serve as a finger piece to turn the valve. The case sections when extended, as inclicated in Figs. 3 and 4, serve as'a stove base or burner support and may be suitably supported elevated 0d the ground by a pair of legs or props 47.. These parts are in the form of bail elements generally U-shaped, as indicated in dotted lines in Fig. 1, having thearms thereof. projecting through openings 48 in the wallsof the case's'ections and having the free ends thereof out-turned to provide trunnions 49 pivotally received in openings provided in the walls of the case sections adjacent the openings 48.- The free ends of the armsof the bail elements 47 are also slightly hooked, as indicated in Fig. 4, so as to lie flush alongside the case (when folded in, as shown in Figs, 1 and 2. The

openings 48 are elongated and serve to limit the movement of the bail elements frominoperative to operative position, as will be clear in Fig. 4. The openings have their opposite ends offset so that an intermediate projecting portion 50 is provided over which no i the arms of the bailelement have to ride in moving from one limit position to the other. In so doing the arms are flexed so'thatthey tend to spring into their limit positions when. moved close to such positions and are yieldinglyheld against movement away from such positions. A lateral extension 51 is provided I on at least one of eachpair of openings 48 to facilitate entering the ends of the arms of the bail element therein when assembling the stove. Obviously the construction described is extremely simple and practical for the purposes intended asthe'legs or props lie flush alongside the case when moved to inoperative position and may be extended quickly to an operative position for support. ingthe stove. When moved to either position the legs or props are not apt to require the resilience of the arms thereof is sufficientto insure their staying in position.

In Fig. we have shown a modified or alternative construction where, in addition to burners 21 and 2 l,'a third burner 52 is provided on the manifold of the burner 2d. The manifold 22 is offset at its inner end, as indicated at 58, to provide room for the burner 52 when the burner 24 is folded alongside the burner 21. The two manifolds are pivotally connected in a manner similar to the connection of the manifolds 22 and 25. The fuel for the burners is supplied from-the tank which has its delivery tube 32. communicating with the inner end of the manifold 25 at 8%. The burner 52, similarly to the burner 21, is not arranged to be put out but operates at all times to preany attention as heat the fuel for vaporization. The burners 21 and 24 are controlled by valves operated by the finger pieces 44- pivotally connected with the links 43. This camp stove is otherwise the same in construction as the other.

It will be observed that the burners, when.

arranged in operative positionfor use, are disposed in alignment with the burner 52 substantially midway between the burners, all three burners being arranged in the middle of the case beneath the grates 10.

It is believed that the foregoing description conveys a clear understandingof the invention and of its principal features and advantages. lVhile the constructions illustrated have been chosen for purposes of the present description as embodying the novel features herein set forth, it will be clear that many changes may be made both in construction and arrangement of parts. so that our invention is not to be considered as limited to the specific constructions illus-- trated. i

We claim:

1. In a camp stove, the combination of a carrying case comprising hinged. sections arranged to be unfolded to provide a stove base, and a burner mounted in one of said sections having a second burner pivoted,

position alongside'the same in substantially the same extended operative position in the other section in substantially the same horizontal v plane.

approximately halfway their coextensive operative relaburners 1n tion. p

In a camp stove as set forth in claim 1, the provision on one of the burners of third burner ad acent'the pivotal connection.

between the two burners so as to be disposed end horizontal plane therewith to. an

approximately halfway between the said to-dispose both burners on one line at upproximately the middle of the case sections.

5. In a camp stove as set forth in claim 1, the provision of the pivotal connection between the manifolds of said burners at such an angle that the pivoted burner swings in a plane an angle to the longitudinal axis of the two sections of the case whereby to dispose both burners on one line at approximately the middle of the case sections, and a thir-l burner on the manifold of one of the other two burners arranged in the operative position of said burners to be disposed substantially midway between the first two burners and also in alignment therewith.

6. In a camp stove, a carrying case comprising a main section in the form of a shallow'tray having acover section also in the form of a shallow tray, said sections being hinged together at one edge of corresponding side walls thereof so as to fold to coextended position to provide a stove base, a burner mounted in the main section, a second burner pivoted thereto and arranged to be moved from an inoperative position alongside the same and substantially in the same plane therewith in the main section to an opera-tiveposition in the cover section coextensive with the main burner and again in substantially the same plane therewith, and means for holding said sections in rigid coextended relation to support the burners for operation.

7. In a camp stove comprising a carrying case arranged to serve as a burner support, means for supporting the same elevated off the ground comprising props each in the form of a generally U-shaped bail element having'out-turned free ends for pivotal en gagement with the sides of the case section, said ball element being movable from a pos1- tion' alongside the case section to a position making an angle therewith, there being openings in the wall ofthe casesection to receive the free ends ofthe bail element for such swinging movement, said openings being elongated and one end of said openings serving to limit the movement of said bail element to its operative position by the engagementof the arms thereof with the ends of the openings, the intermediate portion of the openings 7 being conformed to cause a flexing of the arms of the bail, element whereby the bail-element springs into either its inoperatwe or its operative position from an intermediate position and is held in either of the limit positions.
